Cannot push my git project to empty repository in Bitbucket

Question

I have a problem in my Bitbucket account, which is cannot push my first git project..

I followed the steps of pushing a new git project:

• first command line : git remote add origin https://said_bous@bitbucket.org/said_bous/landing-page.git , it works right.
• Than the second command: git push -u origin master .. Oops not working and show to me that note: "key_load_public: invalid format"

I think that my private key in openssh format, and my public key correct because Bitbucket accepts it!

I don't know where is the problem...
